Calibrachoa plant named ‘KLECA22491’

ABSTRACT

A new Calibrachoa plant particularly distinguished by having a large white single flowers with a semi-trailing habit, is disclosed.

Genus and species: Calibrachoa sp.

Variety denomination: ‘KLECA22491’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct variety ofCalibrachoa, botanically known as Calibrachoa sp, and hereinafterreferred to by the variety name ‘KLECA22491’. ‘KLECA22491’ originatedfrom a controlled-cross between the proprietary female Calibrachoavariety ‘KLECA12235’ (U.S. Plant Pat. No. 25,287) and the maleCalibrachoa variety ‘KLECA17002’ (unpatented).

In August 2015, two Calibrachoa parental lines, the female variety‘KLECA12235’ and the male variety ‘KLECA17002’ were crossed via acontrolled cross in Stuttgart, Germany and seeds were obtained. Theseeds were sown and plants were grown for evaluation. A single plant wasselected in May 2016 and subsequently named ‘KLECA22491’. In June 2016,‘KLECA22491’ was first vegetatively propagated by cuttings. ‘KLECA22491’was found to reproduce true to type in successive generations of asexualpropagation via cuttings.

SUMMARY

The following are the most outstanding and distinguishingcharacteristics of this new variety when grown under normalhorticultural practices in Stuttgart, Germany.

-   -   1. Large, single white flowers; and    -   2. Semi-trailing plant habit.

DESCRIPTION OF THE PHOTOGRAPH

This new Calibrachoa plant is illustrated by the accompanying photographwhich shows a close-up of the whole plant. The photograph is of a10-week-old-plant grown in in Stuttgart, Germany in May 2019. The colorsshown are as true as can be reasonably obtained by conventionalphotographic procedures.

DESCRIPTION OF THE NEW VARIETY

The following detailed descriptions set forth the distinctivecharacteristics of ‘KLECA22491’. The data which define thesecharacteristics were collected from asexual reproductions carried out inStuttgart, Germany. Data was collected on 8-week old plants aftertransplant in Stuttgart, Germany May 2022. Color references are to TheR.H.S. Colour Chart of The Royal Horticultural Society of London(R.H.S.), 5^(th) edition (2007).
